In this way, scripting can assist with rapid realization and "Proof of Concept" in the early phases of a project. A variation of microgeometries is analyzed by an analytical method and an interactive selection allows the identification of a desired result. These data allow an analysis of the load distribution along the contact lines. The resulting data are passed on to the more complex analyses without obstacles between the different programs. The aspects of high load carrying capacity and low noise excitation shall be connected. A result in this detail is computed by covering each contact between roller and raceway. The FVA drive technology software is now even more powerful, with an extended range of calculations and CAD export capabilities.

Skip to main navigation Skip to main content. Determining the ratios of the stages is an optimizing task that is performed by the program GAP according to suggestions by Winter [14] or Linke [13].

The software accelerates development processes and enables even more detailed calculation results. The load distribution resulting from the calculation is used to evaluate load distribution factors according to ISO Succession of design steps:. The Formula Student is an international design contest that gives students the opportunity to apply what they've learned parallel to their studies. The process described in this paper starts with rough design methods and successively proceeds to more detailed methods.

A different approach, e. RIKOR allows the calculation of shaft deformation, bearing deflection, tooth flank modifications, load sharing in the tooth contact, damage-related stresses and contact pattern of spur, helical and double-helical gears. The common approach neglects the shear forces on the deformation which is reasonable for slender shafts. Analysis of Ripple on Noisy Gears.

Since each aspect stllus leads to a tight definition of the modifications, a compromise has to be found. Monday, September 30, Hard Fact of Hard Rack Milling.

This is easily sstplus with the STplus-suite [8] that includes the geometry calculation and the standard calculation as well. Being most precise requires a time step integration to account for the changing mesh stiffness. Since sufficient load capacity has to be granted, the parameters available for variation and optimization of the flank modifications are very limited.

A simple approach is documented, a more thorough method is named but not discussed in detail. This may lead to partial contact pattern under partial load and may have a negative effect on noise excitation.

The differences are quite small, so much finer determination of the modification parameters is necessary in order to minimize noise excitation in comparison to achieve a good load distribution. Refurbishing Wind Turbine Gears. This goal is reached by solving the system of equations with an even load distribution as input and the microgeometry as unknown vector. Finally, the goals high load capacity and low noise excitations are reached by designing flank modifications.

For increasing normal module, that influence gets less significant, since other parameters clearances, deformations amount to most of the resulting deviations in contact. The programs from early design stages provide data for latter, more complex steps and programs. Fairfax Street, SuiteAlexandria, Virginia Site Safety October 1, With funds of the Forschungsvereinigung Antriebstechnik e.

The goals load capacity and noise excitation meet at the design of flank modifications. The FVA-Workbench is a simulation platform for the modelling, parameterisation, calculation, and dimensioning of gear units. Applying the modifications for sufficient load capacity, the tooth contact area and load distribution in the mesh are not acting on the whole flank for partial load.

With given power, low speed shafts transmit a higher torque moment than high speed shafts. The goal here is to reach a design that is compact and light.

Dimensions of shafts and bearings are covered only by rough estimate at first. For each meshing position, the influence of the environment shafts, bearings, housing is superposed. The focus in this paper will be the high stplua stage.
